Step 1 Line a 13-by-9-inch pan with foil, leaving a few inches hanging over the edge of the pan. Grease the foil.
Step 2 In a saucepan, combine the sugar, butter and evaporated milk. Over medium heat, bring the mixture to a rolling boil, stirring constantly. Continue to boil for 5 minutes, still stirring constantly.
Step 3Remove from heat, and stir in chocolate chips until melted. Add the marshmallow creme, vanilla and peppermint extract, stirring well. Quickly, gently fold in about a cup of mini-marshmallows.
Step 4Pour into pan and spread out evenly. Top with more mini-marshmallows and crushed peppermint candy, and gently press into the fudge.
Step 5Set aside until cooled and set, then pull the foil out of the pan and cut the fudge into squares.
